Vastu is the bridge between man and nature. Everything is made up of basic five elements – FIRE, WATER, EARTH, SPACE, and AIR.
All These elements are found only on earth, and that is why it is the only planet that supports life and nature. If the residential and commercial buildings are constructed without any regards to these elements, then no benefits will be attained. Each of the five basic elements give us a precious gift from the powers of the universe.

All materials in the world, irrespective of their size, shape, color, physical or chemical compositions have embedded their origins from one of the ‘Panchbhootas’. They all enjoy a peculiar vibration level, which evades the intelligence of human beings.

The Vastu science is based upon the laws of nature. The equilibrium we observe in nature is easily perceivable by us in all moving bodies, but unfortunately we are unable to note this equilibrium in static bodies. The basic source of energy of the whole world is stored at the North and South poles. It flows uninterruptedly from the North Pole to the South Pole in the form of magnetic waves. Therefore Southward portion of every building should be higher than the northward portion, in order to avoid any hindrance to the flow of magnetic waves.

Our ancient Vastu Shastra has been founded in such a way, that the inmates can derive maximum benefits from sun-rays and the energies of the sun like heat light, UV rays – the only reliable source of Vitamin D (Vitamin D is absorbed by the blood directly when the bare skin is exposed to sun), which is vital for sustenance of life on earth.

Uttaraayana and Dakshinaayana are of great scientific importance since daytime will be more than the night time in the Uttaraayana facilitating availability of more sun light.

The Eastern direction assumes a great significance because morning sunrays emit more light and less heat, hence is the best. In the afternoon, the sun moves towards West, and emits Infrared rays, which are detrimental to health.
Thus, due to all these reasons, it is explicitly laid down in Vastu Shastra that more open space, more windows and doors fixed, more balconies and verandahas should be provided towards the East and the North side, than in the South and the West side.

The most important aspect considered while formulating Vastu Shastra is the magnetic field of the Earth, which has significant influence on the human life. The human body itself acts as a magnet with the head, the heaviest as North Pole. If the head is directed towards the North while sleeping, the North Pole of the Earth and that of the human body repel each other affecting the blood circulation, causing disturbed sleep, tension and other problems. Thus, it is said by Vastu Shastris that one should not sleep facing his head towards North.
